River wash gravel is put in the drain line trench to aide in water flow. We then put in Polydrain, an air-gap technology drainage board in the cove place where the foundation wall meets the cellar floor. This heavy duty constructed drainage matting is bent and put the wall up and over the trench. It raises water and leads intruding water because of hydrostatic pressure into the subgrade tile program. Following the installation of the Polydrain the trench is sealed with commercial grade concrete.
Olney Interior Basement Waterproofing solutions may also include things like wall systems. Options are a 6 mil polyethylene vapor barrier which is tucked in the Polydrain and installed normally from floor to ceiling. For a cleaner appearance and for walls with a high moisture content Polywall, an extruded resin sheet can be installed. It’s not difficult to clean, 100% waterproof and does not support mold, mildew or bacteria development. For wall areas with high water content, such as corners, problem areas or older structure, Polydrain may be installed complete wall or chest high.
